Atmosphere Layers
I'm the layer where we live and where weather occurs
Troposphere
Weather is measured in this unit of time
Days or hours
A continental air mass is this
Dry
The amount of water vapor in the air is measured by this term
Humidity
This gas makes up 78% of Earth's atmosphere
Nitrogen
I extend to 50 km above sea level and contain the ozone layer
Stratosphere
Climate is measured over this timespan
30 years
In the northern hemisphere, wind moves this direction around a low-pressure system
Counterclockwise
When air rises and forms clouds, this type of cooling occurs
Adiabatic cooling
This percentage of the atmosphere is oxygen
21%
I'm the coldest layer, starting at 50 km above sea level
Mesosphere
This measures changes in air pressure to predict weather
Barometer
These are wind zones between 30°N and 60°S latitude
Trade winds or Prevailing westerlies
This is the boundary between the troposphere and stratosphere
Tropopause
This gas causes the greenhouse effect by trapping heat
Carbon dioxide
I have very high temperatures due to absorption of ultraviolet radiation
Thermosphere
This measures wind speed in weather monitoring
Anemometer
This is the boundary between air masses with different temperatures
Front
When two air masses of very different temperatures meet, this forms
Orographic lifting or Convergence
This gas makes up 0.93% of the Earth's atmosphere
Argon
I'm the boundary where most rising water vapor does not reach
Tropopause
This measures the distance to and location of precipitation
Weather radar or Doppler radar
These are fast-flowing winds in the troposphere between air masses of very different temperatures
Jet streams
This equals the amount of radiation reflected by Earth's surface
Albedo
These molecules exist in trace amounts but are essential for understanding atmospheric phenomena
